String bearing and tremolo device method and apparatus for stringed musical instrument

A method of manufacturing a stringed instrument, comprising the steps of:

• providing a body;
• connecting a plurality of witness points to said body, said witness points consisting of elements taken from the group of bridges, slant bridges, inverted slant bridges, floating bridges, saddles, nuts, frets, fingerboards, dampers, soundboards, and capodastro;
• connecting a plurality of strings from end to end on said body so as to cross and be able to be placed into contact with said witness points;
• attaching string bearing members to at least some of said witness points, said string bearing members enabling axial motion of said string;
• and
• supporting at least some of said string bearing members with saddle assemblies conditioned to provide horizontal, vertical, and axial position adjustments or fixed position, said saddle assemblies comprised of material for preventing said saddle assemblies from vibrating axially relative to said string bearings.

A tremolo device for constant inter string pitch correction and pitch trajectory control in combination with a stringed instrument comprising:

• a plurality of non-linear string tension devices, one per string;
• said non-linear string tension devices providing conversion means for tremolo bar input angle to individual string tensioning in the axial direction;
• said non-linear string tensioning devices providing tensioning displacement as a function of said tremolo bar input angle;
• said non-linear string tensioning devices comprising a multiplicand from the group comprised of square of 2.phi./K1 for chromatic pitch trajectory control, and square of .phi..times.K2 for linear pitch trajectory control, and .phi..times.K3 for natural pitch trajectory control, whereas .phi. is the tremolo bar input angle and K1, and K2, and K3 are the string's chromatic, linear, and natural pitch trajectory coefficients;
• and
• said non-linear string tensioning devices including means for termination of said strings.
